Low WVT Adhesive Film
Product Overview
This adhesive film uses an adhesive with an extremely low water vapor transmission rate compared to general acrylic adhesives. By using this adhesive film, the impact of water vapor on the bonded components can be reduced.
Product Features
Feature 1
Low moisture permeability
Compared at the same thickness with general acrylic adhesives, the water vapor transmission rate is approximately 1/3. The thicker the adhesive layer, the higher the water vapor barrier performance.
Feature 2
High-cleanliness production
It is manufactured in a high-cleanliness environment cultivated through years of experience in producing polarizer protective films.
Feature 3
Sustainable adhesive
The use of biomass-derived adhesives helps reduce environmental impact.
